Hello, young neuroscientists and their guardians! We a thrilled to introduce a fun and educational activity to celebrate STEM Day. Today we are going to learn about the most complex organ in our body – the brain, by creating an edible model!

The Concept: The Brain

The brain is the control center of our bodies. It’s responsible for processing information, controlling our movements, and regulating our bodily functions1. It has different parts with specific roles. For instance, the cerebrum controls thinking and voluntary movements, the cerebellum manages balance and coordination, and the brainstem connects the brain with the spinal cord and controls automatic functions like breathing2.

Now, let’s dive into our activity where we’ll create a jelly brain model!

Edible Brain Model


  1. A brain-shaped mold (you can find inexpensive ones online)
  2. Two packs of jelly or gelatin mix
  3. Hot water (please ask an adult for help with this)


  1. Follow the instructions on the jelly or gelatin pack to prepare the mix. Remember, handling hot water should be done by an adult.
  2. Pour the mixture into the brain mold.
  3. Let it cool down a bit before placing it in the refrigerator.
  4. Leave it to set for a few hours or overnight until it’s firm.

Now you have a jelly brain model! You can use this to discuss the different parts of the brain and their functions.

Remember: Adult supervision is necessary when handling hot water and sharp utensils. Be careful when removing the jelly brain from the mold.

This activity not only helps children understand the complexity of the brain but also allows them to engage in active learning. Plus, they get to enjoy a tasty treat afterwards!

Let’s celebrate STEM Day by exploring, learning, and of course, having fun. Happy STEM Day to all our future brain scientists!
